We report preliminary results of a procedure to obtain averaged maps of functional activity relative to several rat brains as well as between-groups difference maps. Functional maps are created using the 2-deoxyglucose method. Due to the variability in size, shape and location of structures between brains we have applied a non-linear deformation algorithm under landmark-driven constrains to obtain the matching of the 3-D reconstructed functional volumes. A volume obtained from images of histological sections is taken as reference atlas for the fitting procedure.

Abstract
We report preliminary results of a procedure to obtain averaged maps of functional activity relative to several rat brains as well as between-groups difference maps. Functional maps are created using the 2-deoxyglucose method. Due to the variability in size, shape and location of structures between brains we have applied a non-linear deformation algorithm under landmark-driven constrains to obtain the matching of the 3-D reconstructed functional volumes. A volume obtained from images of histological sections is taken as reference atlas for the fitting procedure.
